Claim 1
Independent Claim
127 words
Apparatus useful for predicting for bodies of water upon the earth's surface the time of flow of currents, the direction of current flows, the strength and duration of the flow of currents, at a given geographic location, which comprises a stator scribed with indicia to form a scale representing a time period in days, and another scale representing hourly heights of the surface level of the water relative to a normal level, a slide scribed with a sinuous wave form of irregular shape representative of the tidal range over the period represented on said stator which can be fitted to and compared with the scale of values on said stator to determine the time of flow of currents, the direction, strength and duration of flow of currents.

Claim 3
Dependent Claim
142 words
The apparatus of claim 1 wherein the stator is constituted of two elongate sheets sealed together along the elongate edges thereof and open within the center to form a sheath within which the slide can be fitted, a front face of one of the elongate sheets is provided with a window through which indicia scribed upon the slide can be viewed, the front sheet of the stator is scribed just below the window with indicia representative of days of the week, and a vertical scale alongside the window representative of tidal range, which indicia can be compared and contrasted with the indicia of the slide to be visually read, to provide for a given geographic location, in terms of the year, month, day and hour of occurrence, exacting information regarding the direction of current flow, the strength, and duration of current flow.
Claim 4
Dependent Claim
86 words
The apparatus of claim 2 wherein the indicia scribed on the slide is in the form of a sinuous wave projected over a number of days corresponding to the number of days scribed on the horizontal scale below the window on the front sheet of said stator, the day and hour over which current flow occurs can be read from the horizontal scale on the stator, and the relative strength of the current can be read from the vertical scale on the stator opposite the window.
Claim 5
Dependent Claim
33 words
The apparatus of claim 3 wherein the relative strength and direction of the current can be read from either, or both, of a pair of vertical scales on the stator opposite the window.
Claim 6
Dependent Claim
160 words
Apparatus useful for predicting for bodies of water upon the earth's surface the time of flow of currents, the strength and periods of flow of currents at a given location, which comprises a stator constituted of two elongate sheets, a front sheet and a rearward sheet sealed together along the elongate edges thereof and open within the center to form a sheath, the front sheet is provided with a window, indicia scribed below the window to represent days of the week, and a vertical scale alongside the window representative of tidal range, a slide which can be fitted within the sheath between two sheets, the slide is provided with a sinuous wave form of irregular shape representative of the tidal range over the period represented on said stator, this scale when compared with the vertical scale of values on said stator is determinative of the time of flow of currents, and the strength and direction of the flow of currents.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
104 words
The apparatus of claim 5 wherein the sinuous wave form representative of the tidal range is a plot made from the predicted hourly heights taken, for any geographic location, from lunisolar tidetable data supplied by the National Ocean Service, any point on the locus of points forming the sinuous wave form can be read on the horizontal scale of the stator to provide the day of the week and hour, and the tidal height read from the vertical scale of the stator such that the ebb and flood tides are readily discernable, as well as the relative strength and periods of flow of currents.
